Abstract

Oil storage tanks are a major structure in chemical industrial complexes. Damage to the structure due to natural disasters or poor management can cause additional damage, such as leakage of chemicals, fire, and explosion, so it is essential to understand the deformation. In this study, data on oil storage tanks were acquired using a 3D laser scanner, and various analyzes were performed for storage tank management by comparing them with design data. Modeling of the oil storage tank was performed using the data and design drawings acquired by a 3D laser scanner. An inspection of the oil storage tank was effectively performed by overlapping. In addition, cross-sectional and exploded views of the deformation were produced to generate visible data on the deformation of the facility, and it was suggested that the oil storage tank had a maximum deformation of -7.16mm through quantitative analysis. Data that can be used for additional work was obtained by producing drawings to be precisely inspected for areas with large deformation. In the future, an inspection of oil storage tanks using 3D laser scanners is quantitative and visible data on oil storage tank deformation. This will greatly improve the efficiency of facility management by rebuilding it.

유류 저장탱크는 화학 산업단지의 주요한 구조물로서, 자연재해나 관리 부실로 인한 구조물의 손상은 화학물질의 유출, 화재, 폭발 등의 추가적인 피해를 야기하기 때문에 변형에 대한 파악이 필수적이다. 본 연구에서는 3D 레이저스캐너를 이용하여 유류 저장탱크에 대한 데이터를 취득하고, 설계 데이터와 비교하여 저장탱크 관리를 위한 다양한 분석을 수행하였다. 3D 레이저스캐너로 취득된 데이터와 설계 도면을 이용하여 유류 저장탱크의 모델링을 수행하고, 중첩하여 유류 저장탱크의 검사를 효과적으로 수행할 수 있었다. 또한 시설물 변형에 대한 가시적인 데이터 생성을 위해 변형에 대한 단면도 및 전개도를 생성하였으며, 정량적인 분석을 통해 유류 저장탱크가 최대 -7.16mm의 변형이 발생하였음을 제시하였다. 변형이 크게 일어난 부분에 대한 정밀 검측대상 도면을 생성하여 추가적인 업무에 활용할 수 있는 데이터를 생성하였으며, 향후 3D 레이저스캐너를 이용한 유류 저장탱크의 검사는 유류 저장탱크 변형에 대한 정량적이며, 가시적인 자료를 제공함으로써 시설물 관리의 효율성을 크게 향상시킬 것이다.
